CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The Civil Aviation Safety Authority or its predecessors issued AD/ROCK-114/8 affecting Gulfstream (Rockwell) 114 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/ROCK-114/8. The cancellation will become effective on 25 September 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the industry. The Act empowers the Governor-General to make regulations in the interests of the safety of air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These directives are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The ADs are crucial for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, assesses ADs issued by the State of Design and, if necessary, issues corresponding Australian ADs. In this instance, CASA has cancelled Australian AD/ROCK-114/8, which affected Gulfstream (Rockwell) 114 model aeroplanes, as the unsafe condition addressed by the directive no longer exists. This cancellation aligns with Australia's obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was required.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These regulations apply to all aircraft and aeronautical products within Australia's jurisdiction, encompassing both the State of Design and the State of Registry responsibilities as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing information from the State of Design and issuing Australian ADs as necessary to maintain the continuing airworthiness of aircraft on the Australian Register. The issuance and cancellation of such directives are made under the authority provided by the Act and the Regulations, and any ADs are considered disallowable instruments as per the Acts Interpretation Act 1901. The scope of these regulations extends nationally, with CASA having the authority to mandate specific requirements for aircraft and aeronautical products to ensure compliance with safety standards. Additionally, the issuance and cancellation of ADs are done without the need for public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, particularly under section 98, allows the Governor-General to make regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and are subject to the Legislative Instruments Act 2003. As per Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for ensuring the continuing airworthiness of an aircraft type, and must provide necessary information to the States of Registry. The State of Registry, in this case CASA, must assess this information and, if appropriate, issue an AD to enforce the requirements of the State of Design.
The obligations under these regulations are multifaceted. The State of Design must ensure that any ADs issued are based on the continuing airworthiness of the aircraft type and must provide all necessary information to the States of Registry. The State of Registry, represented by CASA, has the obligation to assess this information and, if necessary, issue an Australian AD to ensure compliance with safety standards. CASA must also ensure that any ADs issued are in accordance with subsection 84A(2) of the Act. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, thereby streamlining the regulatory process.
In terms of enforcement, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences or penalties for non-compliance with ADs. However, non-compliance with an AD can lead to significant civil and criminal consequences. The potential civil consequences include fines and penalties as determined by the relevant aviation authority, while criminal consequences could include imprisonment, depending on the severity of the violation and its impact on air safety. The exact penalties would be determined on a case-by-case basis by the relevant courts and authorities.
